v3 Enable lodash 'paths' feature

[muschottkey]

According to the documentation, most features were turned off by default to reduce the package size. In order to use your desired feature, you needed to opt in to it.

'paths' feature was set to false. According to lodash documentation, paths feature offers Deep property path support for methods like _.get, _.has, & _.set. If the feature is not enabled, deep property fetching will fail since the methods are replaced with a _.noop method that always returns undefined.

Field attributes depend on this functionality in order to get attributes.label, attributes.input and attributes.wrapper. I also have fields with models like foo.bar which means that these fields will not work since we are able to set the value, but not get the value.

Therefore, I have enabled this option so that we can be sure that vfg.abstractField's value property will always be working whether the model provided is a deep or shallow path.
